Application filed March 12, 1917. Serial No. 154,245.

To all whom it ma concern:

Be it known t at 1, WILLIAM J. Pnox, a citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful. Improvements in Forming and Quenching Machines, of which the following is a full, clear, and exact description, referencebeing had to the accompanying drawings, forming part of this specification.

My invention relates more particularly to that class of machines which are suitable for use in the manufacture of leaf springs.

' One object of my invention is to provide a machine iii-which the discharge of the formed and quenched product is accomplished automatically.

Another object is the provision of means whereby a complete cycle of operations is performed by a single rotation of the main drive shaft.

A further object of my invention is to so construct the machine that the forming or bending process is accomplished independently of the quenching.

Other objects of my invention will appear, and bedescribed throughout the specification.

In the drawings Figure 1, Sheet 1, is a side elevation of a machine embodying my invention, some of the parts being broken away.

Fig.2, Sheet 2, is a plan view of Fig. 1.

Fig. 3, Sheet 3, is a front end elevation in section, the section being taken on the dotted line 3 3 of Fig. 1.

Fig. 4, Sheet 4, is a detail view of part of the driving mechanism, some of the parts being broken away.

Fig. 5,-Sheet 4:, is a sectional plan view of Fig. 4:.

Fig. 6, Sheet 4, is a. front elevation of one of the die heads and its associated parts.

Fig. 7, Sheet 1, is a section end view of Fig. 6 taken on the dotted line 7-7 thereof. Fig. 8, Sheet 5, is a sectional side elevation similar to Fig. 1' but taken, approxivmatelyon a line coincidental with the int'crior surface of the cam 15 of Fig. 3 and looking toward the center offthe machine.

The same numerals of referenceare used to indicate identi'calparts in all the figures.

i Referring moreparticularly to Fig. 1, 1 represents a frame preferably composed of structural steel within which a sheet metal or other suitable'tank mounted, the tank 2 being of a size and shape to fit within the frame 1 and adapted to contain a suitable quenching bath for the quenching of the product of the machine.

j A pair of side brackets 3 and 4 are mounted on the sides of the frame 1 and are provided with, suitable mountings for the various parts of the mechanism to be later described.

A drive shaft 5 is mounted in the upwardly extending portions 6 and 7 of the side brackets 3 and 1 respectively, and this drive shaft is provided with a loose driving pulley 8 which carries a driving clutch memher 9. A driven clutch member 10, and a crank disk 11, are secured to the drive shaft 5 as shown clearly in Fig. 2, the crank disk 11 connecting through the medium of the connecting rod l2'with a cam 13 Which is secured on the rock-shaft 14 (see Fig.3), the rock-shaft 14 carrying a cam 15 which is similar to the cam 13 with the exception that it has no driving connection, the cam 1-3 being located nearthe opposite end of the shaft 11 from the end on which the cam 13 is located.

The shaft 14 is suitably journaled in extensions 16 and 17 of the brackets 3 and 4: respectively.

A pair of end members 18 and 19 are loosely mounted on the shaft 14 adjacent the cams 13 and 15 as clearly shown in Fig. 3, and these end members are connected together by the stationary die heads 20, in this instance there being six of such die heads, the die heads and the end members forming 11 and between the cams 13 and 15.

Each of the stationary .die heads 20 carries a movable die head 21 which is guided in proper relation to the die heads 20 by the gibs 22. An operating extension or lug 23 projects upwardly from each-of the movable die heads 21 and a block 24 is secured to each of the lugs 23 by means'of the stud 25.

Each of the end members 18 and 19 carries a .series of studs 26 upon each of which an operating arm 27 is mounted,- (in the construction shown there being six of the studs and arms for each end member) the arms 27 extending toward the shaft 1-1 and being each provided with a roller 28 carried by a stud 29, the roller 28 lying within the ca groove 30 (Figs. 1 and 3) of the cams 3 and 15,.

The opposite ends of the arms 27 are slotted as at 31 to embrace .the blocks 21 a spool mounted free to turn on the shaft which are attached to the lugs 23 of the movable die heads 21.

It will be observed by referring to the shape of the cam groove as shown in Fig. l. that three of the rollers 28 are in that portion of the can] groove which is concentric. with and near the shaft 1.4-, while the other three rollers are in that portion of the cam groove which is; concentric with but arranged at the. greatest radius from the center of the shaft 1:1- the result be in; that at all times three of the HlOVHlJlQ die heads 21 are in a cloned position While the other three are in an open position.

A driving and locking ring shown in Fi 1, and 3 is carried. by the end member if? and is provided with a series. of. driv in'g nolclnas arranged on the inner di oi the ring and eerie-.5 ol' bincing i f -i arr-an; d on the outer dianim-r tlmreoi' a5; clearly :ahon'n in. Fig. 1.

which me r v .h a. may be either it send or eonsrt of .61195 ol' :nl ustabie means: of which thepro iier currm 100 may be imparted to the wort: Lirough the machine. prefer to employ pair of loading and iarge hooks 51 in connection with each movable die heads, the hooks being ed on a. roeloshaft which snit- 55 and y rifled with. 7 wl'iich so located with stationr'rry .iifiii'! i and 3- d1 charge hoo are the d are prmiid h shown in Figs. and G tor 'il reception oi the lower ends of the hooks when the dies are closed.

To ren' ove the finished productfrom the machine a conveyor 59 is employed and arrai'iged to be driven from any suitable source of power, the. com er 'neferably consist- 3 mg of a link belt which may he provided.

with projections 60, the conveyor oceupy inn ap tiroxim-ately the position showiyinof material which is thicker than that for which the machine is set, be introduced.

The operation-of the machine is as follows:

The drive pulley 8 is suitably connected to any source of power and is drivencon stantly. The operator assumes a position immediately in front of the machine, the front of the machine being the right hand end as shown in Figs. 1 and 2, in which position the operator faces one of the sets of dies as shown in Fig. places upon the hooks 54 a piece of material to be operated on and then depresses the handle 51 to cause theiengagement of the clutch mechanism.

The parts as shown in Fig. 1 are in their proper relation for the commencement of a stroke of the machine and as soon as the clutch mechanism is engaged the shaft 5 is set in operation and its movement imparted to'the cam? 13 and 15 by drawing the upper part of said cam toward the rear of the ma- -chine until such time as the pin of the crank dish 1.1 has reached the limit of its rearward travel This movement of the cams 13 and 15, through the operating arms 27 closes the dies which face the operator and opens the dieswhich are diametrically opposite thereto. The opening of the dies which are in the rear and vertical position causes the engage ment of the finger 57 with the stationary member 58 whereupon the rock-shaft 55 is operated, thereby causingrthe books 54. to assume the position shown by the dotted lines in Fig. 1, in which position a piece of work carried by these hooks is discharged therefrom and on to the conveyor 59.

in addition to closing the dies facing the 'opera'tor and opening the die diametrically opposite thereto, the first half turning of the drive shaft 5 withdraws the dog 37 from the notch of the ring 32 and moves this dog to the rear to a position in which it engages the next notch of the ring 32 and simultaneously with suchengagement the cam rise 41 of the crank disk 11 engages the upper portion of the dog 39 and swings the lower'portion of said og out of engagement with the notch 34 of the ring 32 whereupon, the completion of one revolution of the shaft causes the partial rotationof the whole die structure thereby carrying the previously closeddie downwardly into the tank 2 and bringing the next succeeding die into position to be loaded, the dog 39. then engaging thenextsucceeding notch in the ring 32. and locking the structure against further rotation until the clutch mechanism is again operate v The next operation of the machine shifts ,the, position of the' die structure another sixth of a" turn, thereby bringing the,ma terial which is being quenched into a comy aratively cool portion of the quenching b while at the same time the motion 0 on, a die-structure mounted f carried by said structure, means the die structure serves as a means of 'a-gitat-, ing the bath to prevent localized-heating thereof.

It will be the closing of fore any rotation observed from the above that the dies is accomplished be is imparted'to the die structure and is accomplished entirely inthe rotation of the die struc ture though by the same drivin nism, the result being that all of t e power of the machine is available first for closing the dies and then for rotating the structure thereby permitting the operation of the machine on considerably be required where the closing of the dies was dependent of incidental to and a part of the rotation of' the die structure.

It will be further observed that three of the die heads, namely those which are submerged in the quenching bath remain closed during their successive stages through the bath while the other three die heads remain open and ready to receive the incoming material.
